Volvo: 1986 Volvo 760 Turbo, inner fender, volvo 760

Question
One morning I went to go start my car and it started then it started to die out on me like it was starving for gas then it just died.I tried starting it after that and all it would do is crank over but would not fire.I checked the fuel and the motor is getting the fuel.So I figured maybe it was not getting any spark so I replaced the distributor cap, rotor, spark plugs, and wires.It is getting spark but still will not fire any ideas? Is there any codes that I can get by using the key?any help would be good.

Answer
Greg,
If you have fuel and the pressure is about 42psi and you have spark, test the pulse at the injectors. Using a "noid test light" plug it into the injector wire and see if that is pulsing. If it is not then you may need to try the power stage or the radio suppression relay. Power stage is bolted to the inner fender by the battery, and has a plug that has  about six wires. The relay is mounted either right or left shock tower area is black and has a four prong connector. I think that the part number is 1323592.
